Answer:  a) (5 - 7)²

<u>Step-by-step explanation:</u>

g(x) = x^2          h(x) = x - 7

                         h(5) = 5 - 7

g(h(5)) = g(5 - 7)  = (5 - 7)²         <em>Replace the x in g(x) with (5 - 7)</em>

Type I error

Step-by-step explanation:

A type I error occurs if the null hypothesis is rejected when it is actually true.

Type I                                      Type II

Reject null when true           Fail to reject null when not true

Null hypothesis: ∪ = 30%

Alternative hypothesis: ∪ > 30%

The researchers concluded that more than 30% of first-grade students at this school have entered the concrete operational stage of development and they rejected the null hypothesis.

However, a census actually found that in the population of all first graders at this school, only 28% have entered the concrete operational stage.

A type I error has been made because in actuality the null hypothesis was true but was rejected.
